[R] [R-pkgs] formatR: farewell to ugly R code... Problem with too old ver. of Gtk

[Yihui Xie]

Sorry, I was thinking about GTK+ and RGtk2, then they got mixed up in
my mind to the strange animal "RGtk+"...

I noticed a few users had troubles with installing RGtk2, so I removed
the strict dependence on 'gWidgetsRGtk2' in the next version of
'formatR' (0.1-4). Users can specify other types of GUI's now. For
example, a screenshot for the Java interface is here:
